The capacity to synthesize alpha-D-galactosidase (EC 3.2.1.22), alpha-D-mannosidase (EC 3.2.1.24), alpha-L-fucosidase (EC 3.2.1.51) and beta-D-acetylglucose aminidase (EC 3.2.1.30) was tested among 100 different cultures of soil microscopic fungi and actinomycetes. Two genera of micromycetes, viz. Scopulariopsis and Aposphaeria, which had not been known as producing alpha-D-galactosidase, were found, as well as several new species of the genus Penicillium: Pen. canescens, Pen. claviforme, Pen. cyclopium, Pen. daleae, Pen. frequentans, Pen. piscarum, Pen. simplicissimu, Pen. thomii.

İnsanlığın karşı karşıya kaldığı en önemli halk sağlığı sorunlarından biri olan ilaç direnci, antilayşmanyal ajan geliştirmede yeni stratejileri ve yaklaşımları zorunlu kılmaktadır. Dışa atım pompa inhibitörleri (DAPİ) ve diğer aday ajanlar ile ilgili gelişmeler umut verici olmakla birlikte, mevcut antilayşmanyallerin kullanım sürelerini ve etkinliklerini artırabilme arayışları da devam etmektedir. Bu çalışmada rezerpin (REZ), berberin (BER) ve verapamil (VER) olmak üzere üç adet DAPİ'nin antilayşmanyallere etkisinin araştırılması amaçlanmıştır.

The National Academies of Sciences, Engineering, and Medicine (NASEM, 2021) milk protein yield (MPY) prediction equation includes independent and additive effects of digestible energy intake and absorbed EAA. Our objective was to evaluate the NASEM MPY prediction and EAA use efficiency in Holstein cows in pens from commercial farms. Data collected from 12 Brazilian herds were used.

Calcium (Ca) is necessary for bone health and metabolic functions in poultry, however, the extent to which it can be utilized varies among feed ingredients. The goal of this study was to determine the apparent ileal digestibility (AID) and standardized ileal digestibility (SID) of calcium in wheat and soybean meal (SBM) in young quail chicks using a direct method. Three dietary treatments were used in the experiment: a calcium-free basal diet to determine endogenous calcium losses, and two diets with either wheat or SBM as the primary calcium sources.

This systematic review compares the health, welfare, and behaviour of dairy cows in year-round loose housing systems against those kept in other housing systems in temperate regions. Year-round loose housing systems comprised housing where dairy cows had no access to the outdoors or only had access to a yard, pen or run. The comparator housing systems also comprised housing with and without outdoor access (including grazing).
